How to Fix Wallpaper Bubbles

Fixing wallpaper bubbles or bumps is a simple, five-minute process. Knowing how to fix wallpaper bubbles and bumps prevents further damage like tears or rips. Wallpaper bubbles occur when a weak bond between the wallpaper and wall causes the wallpaper to lift or when a glob of wallpaper paste wasn’t smoothed out when the paper was hung.

To fix an air-filled wallpaper bubble, you'll need a utility knife, a syringe, glue, a damp sponge, and a roller.

Use the utility knife to slit the bubble.

Push down on the bubble to remove the air from the bubble.

Push down on the bubble to get all the air out from under it. If you only just hung the paper, try to press down on the bubble without applying more glue. If that doesn’t hold, then use some glue in a syringe.
